Which frequency correctly describes sprinkler system testing?

• A. Annually
• B. Monthly
• C. Quarterly
• D. Weekly

Answer: (C)

Regular testing intervals for sprinkler systems are set to balance reliability with practicality. Quarterly testing is the standard cadence for routine sprinkler system testing because it provides timely checks of critical functions—ensuring the water supply, pressure, and alarm/supervisory devices and control valves operate as intended—without the overhead of more frequent testing. Weekly checks are generally excessive for a fully installed system, monthly checks are typically reserved for other systems or specific components, and annual testing is for more thorough inspections conducted less frequently. Therefore quarterly is the best fit for routine sprinkler system testing.
